My guess is that it could well take a lot more than a minute to load 41 updates.

Try again!

I tried again and waited 15 minutes this time. But I didn't got my hopes up because when I did a fresh install, Mint Update found 253 updates and these where loaded within seconds. But like I said, I waited 15 minutes and checked again. Nothing. Mint Update was stuck like a brick in the wall. Had to use force quit to close down.
